The diagonals of a parallelogram bisect each other.
True
The diagonals of a parallelogram bisect each other.
Given - ABCD is a parallelogram.
To prove - AE=ED and BE=EC
Proof -
In △ ECD and △ EBA
∠ ECD = ∠ EBA (alternate interior angles )
∠ EDC = ∠ EAB (alternate interior angles )
AB = CD (Opposite sides of a parallelogram are equal)
∴ △ ECD ≅ △ EBA ( by ASA congruency)
∴ AE=ED and BE=EC (c.p.c.t)
